This invention relates to a Wire coiling machine and has for its object to afford mechanism for winding solder wire or Vother forms of Wire on to a spool or into a coil and automatically cutting the Wire and stopping the machine When a'predetermined weight or length of Wire has been Wound into the coil.

Solder Wire is Wound on to spools or into coils according to weight to produce a half-pound coil, one-pound coil, or a ve-pound coil, and the practice heretofore in coiling such wire has been for the operator to control all operations of the machine manually. The Wire has been coiled on a machine including a rotatable winding spindle and a reciprocating feeding carriage, the back-and-forth movements of which have been controlled manually bythe operator, Who reverses movement of the carriage manually upon reaching the ends of the coil or spool and stops the machine, also cutting the Wire manually when the estimated amount has been Wound. This necessitates having to cut off an amount when the Weight of the spool is excessive or to add Wire when the weight is decient, and it is a purpose of this invention to eliminate the necessity of the operator performing these operations, and to render the measuring and cutting of the wire and stopping of the machine entirely automatic.

-Another object of the invention is to enable automatically Winding solder` or other wire into coils of predetermined Weight or length in such aT Way-that-the length of wire is accurately measured during Winding and the wire cut, also stopping the machine when the exact length has been Wound on the coil.

"A further purpose of the invention is to afford a mechanism in which cutting of the Wire and stopping the machine is automatically determined by a predetermined Weight of Wire resulting from measuring a predetermined length in relation to diameter of the wire.

' Still an additional object of the inventionis to afford a mechanism in which the automatic wire-cutting and motor-stopping operations are L the coil. for the xed number of turns of the control wheel. A,

17 claims. (C1. 242-25) Another purpose of the invention is to provide mechanism in which the Wire-feeding and cutting mechanism is mounted on a carriage that` is automatically reciprocated as the wire alter'- nately reaches the ends of the spool or coil and to so relate the carriage-reciprocating means to the Wire-cutting and motor-stopping mechanism that the motor is always brought to a standstill when the carriage is at the starting point of its travel, the motor not being stopped until after' the cutting mechanism operates, with the result that the wire is automatically severed when the predetermined Weight has been Wound into the coil and thereafter the motor continues to op-v crate until the carriage reaches the starting point of its travel where it is in position to receive a` fresh length of Wire for coiling, and thereupon the motor is automatically brought to a standstill.

Still an additional object of the invention is to provide effective cutting instrumentalities for automatically severing the wire after a predetermined length has been coiled, together with practical and eflicient means for measuring the length of wire as it is fed and connecting such measuring means with the Wire-cutting mechanism so that the latter is operated after al xed number of turns of the measuring means or control wheel, which latter is adjustable for different diameters and Weights of Wire.

Another purpose of the invention is to afford a machine of such design that it is practical and' economical to manufacture, can be easily op-1 erated and controlled, and which embodies parts that lend themselves readily to all the necessary; adjustments required for coiling Wire of different.' alloys, different weights, and different diameters, so as to produce a coil vof accurate weight for any selected diameter and weight of Wire.

To these and other ends, the invention con-4 sists in the construction and arrangement of parts that will appear clearly from the followingv description when read in conjunction withv the accompanying drawings, the novel features be ing pointed out in the claims following the speci cation. v

Referring more particularly to the drawings in which like reference numerals refer to the same parts throughout the several views and to Figs. 1 and 2, I designates the base of the ma.- chine on part of which is mounted a suitable tailstockV 2 and headstock 3, between which the spool or coil is supported. The headstock 3 is mounted upon and rotated by a spindle driven by belt 4 from a motor shaft 5, operated by an electric motor 6, while l designates a friction brake controlling the motor shaft of motor 6 and acting normally to hold the motor shaft stationary through the instrumentality of a spring, not shown. 8f yis a solenoid in the motor circuit and connected to the brake '1, acting when en er-l gized upon starting the motor 6 to overcome the action of the spring and to release the brake I from engagement with the motor shaft.

'Ifhe spindle on which the headstock 3 is mounted also` operates through change gears in a` change-.gear box Q to effect reciprocation of the cutting mechanism carriage to be described later, `and to1 this end said changel gears rotate a shaft I-I, see Fig. 2, which in turn drives shaft I2 that carries a worm I3, see Fig. 3, which engages and drives a worm gear I4 mounted upon the` vertically disposed cam shaftA I5', see Figs. 2,. and 4, upon which are keyed the twor cams I6. and Il that are selectable by adjusting the. cams vertically, to impart the desired reciprocating movement to the carriage on which the wirefeeding and cutting mechanisms are mounted.

In order to effect such adjustment, the cams are` adjustable vertically by means of adjusting cams I8, see Fig. 2,` mounted on an arbor I9 which carries a handle 2l, see Fig. 3, for turning the cams I8 to move the cams I6 and l? upwardly or downwardly, and bring either cam t6 or I'I intol position for engagement at opposite points with rollers 22-` and 23 mounted respectively on brackets 24 and 25, see Fig. 2, which in turn are mounted on the bed 25, see Fig. 3, that supports the carriage on which the wire-feeding andfwire-cutting mechanisms are mounted. The bracket 25 is iXedly mounted on said bed while bracketY 24l is adjustable endwise for cooperation with either of the aforementioned cams I6 and Il, the bracket 24 for this purpose being provided with a nut 2l, see Fig. 2, which threads on to an adjusting spindle 28l carrying a bevel gear 29` that is engaged and operated by a bevel gear 3l connected through an arbor 32 with the 4 adjusting handle 33. Once the adjustment is made, the bracket 24 is in position to engage either the cam I6 or cam II at a point opposite to the xed bracket 25 so that as the selected cam rotates, the brackets and with them the bed 26 and carriage 34 are reciprocated to eiect winding of the wire between the ends of the spool or between the ends of the coil of predetermined length where no spool is used to hold the wire.

Referring to Figs. 2 and 3, the reciprocatory carriage 34 which is moved back and forth in the manner already described by a selected cam, depending upon the length of coil to be wound, is provided with wire-feeding means and wirecutting means that is automatically operated after a predetermined length or weight of Wire has been fed, and the following description has to do first with the wire-feeding instrumentalities.

The Wire indicated at 35 is fed from any source of supply over pulley 35, see Fig. 3, thence around under and in frictional engagement with a control wheel to be described presently, and thence upwardly over, pulley 37 to theV winding spindle or spool to which it is attached when the operation s started, and after the free end 0f the wire has been thusv secured,.the motor is started by operating a suitable starting switch, and continues to Wind the wire as the carriage 34 reciprocates until a predetermined length or weight of wire is wound on thecoil, whereupon the cutting mechanism is automatically .operated to cut the wire Aand stop operation. of the motor.

To accomplish this, the control wheel, see Fig. 5, which is actuated by `rictional engagement with the Wire as the latter 4is fed into the machine, comprises opposite side walls 33 that. are

, fastened to a cylindrical hub 39, and are sprally threaded on their opposed faces as indicated at 4I, said threads 4I acting to support a multiplicity of pins 42 which extend through radial slots 43 in the adjusting reel 44 arranged bef tween the side- Walls 38, see Figs. 5 and 6. Thus by turning the reel 44 in relation to the side walls 3.8 of the control wheel, the 'pins i2 which are located horizontally and afford the effective contacting surface with the wire, are all adjusted radially of the control wheel in order to vary, when necessary, the diameter of the wire-engagging-` surface of the control wheel.

The reel 44 is normally held againstmovementrelatively to the side walls 38v by a spring catch 45V pivoted at 45 on a cap 41 that is xedly connected to the hub 39, while 48 iS a spring normally holding the catch 4 5 in locking engagement with the reel 44. The pins 4 2 which are preferably of cylindrical or partial cylindrical cross-section are cut away. at their outer peripheries, as shown in Fig. 6, inA order to afford a continuously circular contacting surface with the wire as it engages the peripheries of portions of the pins, thus compensating for the spiral dis,- positionv of the. ends of the pins where they are supported in the spiral threads of the side walls of the Wheel.

It will be understood that with the. pins 42A in a certain adjusted position, the periphery of the wire-engaging surface is suchl as to measure a predetermined length or weightY of wire for a given diameter, and if wire of different weight and diameter is to be fedv to the machine, the control wheel is adjusted accordingly by releasing the catch 45 and turning the reel 44:1 relatively to the side walls 38 until the proper. diameter isA obtained, such diameter of the control Wheel being maintained as long as the same weight and f diameter of wire is fed for coiling. y y

The diameter of the effective surface of the control wheel, or adjustment of reel 44, is indicated 'at any time by a dial 49, see Fig. 7, having suitable indicia on its periphery which can be observed through an opening-l in housing 52, the dial 86 being mounted on anrarbor 53 and controlled by a spring 54, while 55 designates a pinion on arbor 53 that is engaged by a rack 56, see Fig. 8, which is suitably guided and carries a roller 51 in engagement with the outer peripheries `of the pins 42 so that any adjustment of the pins 42 radially of the control wheel effects a corresponding -positioning of the roller 51, rack 56, land indicating dial 49.

The wire-cutting mechanism which will described presently is actuated by electrical means after the controlrwheel has made a fixed number of turns, and to accomplishrthis, the cap 41 whichvis connected to the control wheel engages thesquared endof a spindle 58 which is thus rotated by the control wheel. The spindle 58, see Fig. 5, carries at its opposite end a worm 59 that engages and rotates a worm gear 6I, and worm gear 6| has xedly connected therewith a cam 62, see Fig. 9, which during rotation of the worm gear 6I engages a micro-switch 63, the latter being normally open and acting when closed by cam 62 to close a circuit to a solenoid which effects movement of the Wire-cutting mechanism.

. The cam 62 is arranged to operate the microswitch 63 once for each complete turn of the wormv gear 6I corresponding to fty turns of the control wheel, which number of turns produces a one-pound wire coil, and when it is desired to produce a half-pound wire coil which requires operation of the micro-switch for every twentyfive turns of the worm gear 6|, it is necessary. to actuate the micro-switch 63twice during each rotation of the worm gear 6| and in order to bring this about, there is provided an additional cam 64, see Fig. 9, fixed upon spindle 65 which extends through. the worm gear 6l and cam 62.V The spindle 65 is movable against the action of spring 66 in order to release cam 64 from its normally locked connection with cam 62 and can then be turned through 180 until the cam 64 islocked to cam 62 in theposition shown in dotted lines in Fig. 9. This adjustment is possible 'by the plunger-head 61 on arbor 65 extending outside the casing and accessible to the operator, so that when it is desirable to effect operation of the micro-switch twice during each rturn of the worm gear 6I, the spindle 65 is pushed inwardly and cam 64 turned as already described until it is opposite cam 62 and in the same vertical plane. Then as worm gear 6| rotates, the micro-switch 63 will be actuated twice during each revolution of Vthe worm gear, thus effecting a wire-cutting operation and stopping of the motor at every twenty-five turns of the control wheel and forming a half-pound coil instead of a one-pound coil for every fifty turns.

Actuation of the micro-switch 63 closes a cirn cuit to solenoid 68 which effects operation of the wire-cutting mechanism in the manner that will now be described.

The cutting mechanism is mounted upon a supporting plate 69, see Figs. 10 and 12, which is adjustably supported on arm 1I, which in turn is vertically adjustableon bracket 12, that is. mounted on the reciprocatorycarriage, and theA cutting mechanism includes a fixed knife 13 car-- ried by the extension 14`on the plate 69, and a movable knife 15 mounted on an arm 16 which is pivotally mounted upon a post 11 for oscillatory movement, see Fig. 11. The arm 16 carries a pivoted block 18 to which is adjustably connected a vertical operating rod 19, the lower end of which has an angularly bent portion 8|, see

tionary until the control wheel has made the. fixed number of turns as already described to opV erate the micro-switch 63, whereupon the sole, noid 68 is energized to move link 84 and actu--r ating bar 83 downwardly and thus operate the movable knife 15 into cutting engagement with stationary knife 13 and sever the wire, which during the feeding operation moves between and past the knives in position to be cut when the cutting mechanism is operated.

The circuit to solenoid 68 is independent of the motor circuit, and it is desirable to open the motor circuit and stop movement of the motor immediately after the cutting mechanism has operated, and in such manner as to bring the cam I6 or I1, Whichever is selected for operation, to its initial position with the carriage at the beginning of its travel ready to receive a new length of wire. To effect this operation, Vthe, motor circuit is controlled by another micro-switch 85, see Figs. 4 and 13, which is engaged and operated during each rotation of the cam by a tubularV stop 86, see Fig. 13, that is slidably supported on the adjustable plate 81 and is engaged by a pin 88 carried by the lower cam I1 so that as the cam rotates, the pin 88 carries the stop 86 with it, the latter sliding over the supporting plate 81 and engaging the micro-switch once during each turn of the cam. By having pin 88 vertically slidable in the tubular stop 86, the arrangement is such that the micro-switch is operated in the same fashion when the lower cam I1 is in posi-i tion for controlling the reciprocating carriage movements Aor when the upper cam i6 is in position for controlling the reciprocating carriage movements.

It is necessary that the micro-switch be effective only after the cutting mechanism is operated since the micro-switch 85 is engaged and operated during each rotation of the cams,l but stopping of the motor is to be effected only'l at the completion of the cycle after the required number of convolutions have been wound on the coil and the cutting mechanism operated. This' is effected by arranging micro-switch 85 in a circuit that is normally open and closed only after the solenoid 68 is energized to effect operation of the cutting mechanism. To accomplish this, the solenoid 85 is in a circuit controlled by a micro-switch 89 which is normally open and.

in the path of the plunger of solenoid 68, sothat during reciprocating movements of the carriage' and coiling of the wire, the operation of mircoswitch 85 by rotation of cam l1 has no effect on the motor but after the cutting mechanismr 7 closes the :circuit .between the .motor and micro-switch :85, thus .rendering the latter ericctive `to open themotor circuit lupon the next :engagemenil Iof Athe micro-switch ili' Aby the 'tubular stop 36 during rotation of the cam. This lstopM ping operationof the motor takes place 'at such time `that the cam will have reached the neutral position illustrated .in Fig. .4 to bring thecarriage back .to the .beginning of its travel, 'and any slight overrun of the `motor :isicompensated for by mounting .the micro-switch 535 on the aforementioned adjustable Vplate 8l which is supported `in posts 9i, .see Figs. 4 and 1?., :and .carries a gear segment .on Vits .outer :edge `that is .engaged and operated `by 1a pinion '9.2 .connected to a knurled wheel 153 that is .engageable through `.an opening 94 in .the housing to permit adjustment .of the plate :81 and :micro-.switch .85, :depending upon the Aspeed :ci the motor. After such adjustment is .once inade, the Amotor will always vstop at a point 'suchthat the `control .cams l5 .and 'il are in .their neutral .positions .or .initial positions. stoppage .of the motor .is insured Lby the brake l previously .referred to, the brake l .being brought into .play when the motor is stopped .and solenoid 8 which .is in the motor circuit deenergized .to release .brake l which .is thereupon l.spring-actuatcd to engage the motor shaft.

In order to vary the .tension on the wire in accordance with the character and iiiexibility of the wire, the .guide pulley 3l., the .cutting mechanism, and the .controlwheel are adjustable vertically and to-accomplish this, the .control wheel and micro-switch -cam .mechanism .are .all .sup-

por-tedfon a bushing 95 which is adjustable vertically in a slot 9% of bracket l2, see Figs .5 and 150,'whilethe arm ll is held Yagainst :the bracket T2 in interlocking engagement with a lug ldl on the bushing -95 -by means of a nut -88 that engages the threaded end of the bushing and maintains the latter tightly against the supporting plate 99 which in turn is `clamped against the bracket. Any desired adjustment of these parts'to elevate the control wheel and arm l! or to change the angular relationship-of the latter can be had by loosening nut 98 and moving the bushing S5 endwise to disengage the interlocking lug 9'! from the recess in the arm ll, thus permitting turning the latter to any desired position and elevating'the arm together with the control wheel to 4any position of vertical adjustment in the slot 95 whereupon the 'nut 98 is tightened to secure the parts in such adjustment. 'The plate S9 :is adjustable on arm 7l, see Fig. 10, by means of an adjusting `pin lill carried by the plate 89 and engaging any one of a ,series of openings H12 arranged in the arm .ll so that the plate t9 can always be disposed in a substantially horizontal or any desired position in relation to the arm lii when adjustment of the latter is effected.

.in .order .to .adjust the control wheel and .cutting mechanism vertically of the :bracket l2, see Figs. 3 and l0, the bracket is provided with a series of openings |53 .that receive a springactuated lccking pin H34 carried by the supporting housing and acting to holdthe :control wheel and cutting mechanism assembly many selected position -of vertical adjustment `on bracket l2.

When the machine isemployed for coi'ling wire on a spool, Ythe spool ,is .gripped between a tailstock l2 and .hcadstock 3 by moving 'the tailstock endwise to `bring the latter into engagement `with the .spool and when the wire .is to be-'coiledindependently of a.'spo.ol,;it iis engaged vwith a 'notch [05 inthe end nf a spindle 106 forming part Iof Cil the :tailstock and the .latter ybrought .into .interlocking engagement with the headstock, while |01 indicates a stripper through which the spindle |06 is movable endwise and which facts .to .remove the coil from Vthe tailstock spindle after ycompletion of the winding and cutting operation and upon 'withdrawal of the tailstock.

'The operation of the machine briey is as follows: solder Wire or yother suitable alloy or metal -wire of any -diameter being fed from .a basket, spool -or other source of supply and the desired .adjustments fof the .control wheel .and control .cam having :been made, depending upon the .size of the lcoil and the diameter and weight of the wire to be fed, the proper cam is selected, either Acam I6 or cam ll, depending yupon the length of spool or coil .to .be wound, .by elevating or lowering fthe .cam .unit :to .selected position, following which the Vwire is threaded over pulley 3B, under .and .around the rcontrol wheel, and thence .over pulley ;3.1 and interlocked with the tailstock spindle vor spool, .whereupon the .starting switch is .operated and the -wire .is fed .and -coiled upon .the spindle .during rotation .of the latter and reciprocating movements Vof the .carriage until .the predetermined length lof 'wire has fbeen coiled. When the wire `has effected the given number of .turns of vthe control wheel, microswitch 63 is operated by cam 62 or 64, and .the cutting mechanism actuated through thesolenoid E8 to .cut .the wire. Immediately Aafter cutting of 'the wire vand assoon as cam l1, .or cam l, has about reached its neutral position, microswitch is .operated to open the motor circuit and stop the motor whereupon the 'wire coil .is removed A,by disengaging the tailstock, .and the parts are ready for afurther operation.

While `the invention has .been described with reference to lthe structure herein shown, it .is not limited .in this respect, and this application .is intended to vcover such departures, modifications, or adaptations as may come within the intent ofthe improvements or thescope of the following claims.
